Abstract

The behavior of a one-dimensional plasma photonic crystal in exposure to electromagnetic waves is investigated in this paper. This photonic crystal consists of alternating layers of dielectric and plasma which are exposed to an external fixed magnetic field. The magnetic behavior of a one-dimensional plasma photonic crystal in exposure to electromagnetic waves is investigated in this paper. This photonic crystal consists of alternating layers of dielectric and plasma which are exposed to an external fixed magnetic field. The magnetic field is placed in the direction perpendicular to the layers, and the incidentwave on the photonic crystal will be obliquely and at an angle of θ_0. The incident linear wave passing through the magnetized plasma layer is separated into two categories of right-handed and left-handed circular polarization, which is caused by the difference in the speed of the right-handed and left-handed waves in the direction of the magnetic field. We consider the plasma to be a weakly ionized cold approximation and the effects of the collision of electrons and plasma molecules as a dissipation effect that absorbs part of the wave energy, is included in the calculations. We will investigate the effect of magnetic field intensity, collision frequency, dielectric permittivity and incident angle of radiation wave on the structure of the photon band, reflection and absorption coefficients.
